And now we head overseas because there are new images posing a challenge to america's leadership around the world. Did the syrian government use chemical weapons against its own people, women and children? Is there new evidence? We warn are the images can be disturbing as abc's chief global affairs correspondent martha raddatz tonight searches for the truth. Reporter: The pictures are gut wrenching, the rebels say these are mothers, fathers, children killed while they slept in their homes in a damascus suburb. They say the syrian regime fired rockets against its people carrying poisonous gas, leaving the innocent con vulsing, foaming at the mouth, suffocating. I would be surprised if it turned out to be a fake. Reporter: The images are impossible to verify for certain and the regime say the allegations are baseless but we showed them to a weapons expert. The only explanation I can see is this looks like this fellow's nerves are being destroyed potentially by something like sarin. Reporter: The white house said today it's deeply concerned but the white house has said that before. Almost a year to the day president obama warning syria about crossing a red line. We have communicated in no uncertain terms with every player in the region that that's a ready line for us. Reporter: Two months ago when the white house said it was convinced assad had carried out a small care chemical attack, the red line seemed to blur. Little was done in response. What is not debatable is the human toll. I want to show you some images. Thousands of families streaming out of syria, escaping the bloodshed. Among them, a child, diane, who WILL BECOME THE ONE MILLIONth Young syrian to flee. A sad milestone. It is. Those are amazing pictures, martha and thank you tonight. By the way, as martha knows, 10,000 syrians flee every single day.
